Automatic bushing replacement question
« on: September 25, 2024, 23:48:37 »
Lever has gone floppy and noticed that bushing has perished and disconnected from transmission and the whole thing can pull out from below as pictured!

The bottom bushing can be replaced from below but I guess the top one has to be done from inside ?

I have seen previous posts on this and seems quite doable?

Thanks
H

hi
inside the cabin,  pull up the carpeting around the gear shift.
remove 4 bolts
install new bushing on rod, re connect rod to shift assy
re install from inside cabin  (feed rod down along the trans)

secure 4 bolts, put car in "P"
go under car push trans selector to forward position, connect linkage

Thanks so much sorry I see most of it is done from the top and as you say slide it down from the inside. When I refit the bottom part of it, the transmission connection has to be as far forward as possible -ie as close to the front of the car is park?

Sorry for the basic questions

hi
yes   you need the rod as far forward as possible to make it easy to attached the rod to the transmission..

i put the gear selector in "P"  you can try a different selector position.

I ended up replacing the bushing on my sl this morning.   
the picture shows the entire assy removed from the car.

when re assembling make sure the "lip" on the bushings are facing the correct direction.   towards the shifiter or trans

Matt,
     I'm finally getting around to doing this same repair on my 70 280SL but only the lower bushing, which disenegrated back in May.
Right now I have the car locked in 2nd.   After inserting the new bushing, you recommended moving the gear selector to Park to get the rod closer to the selector knob on the transmission. 

My question is how do I know what gear the transmisson selector plate is in, to match it to Park, Neutral, etc.  I remember seeing a photo/diagram on the forum a few months ago showing what position matches which gear, but I cannot find my way back to that post.

Appreciate any help.

Hi I have replaced both bushings but the shifter does not shift easily through the gate. I suspect the link arm needs adjustment. Is there a way to know the length and the direction that the adjustment screw needs to be tightened to ensure it fits correctly ?

before you unscrew the selector plate from the trans tunnel put the lever all the way rearward. this puts the trans connection all the way forward.  then you can access that connection from under the car.

if it shifted fine before then dont mess with the linkage length.  make sure the linkage rod is installed properly
usually from in the car i kind of guide the rod down and along the trans then set the selector plate in place.
then connect the linkage to the trans , last bolt the plate in place.

the shift rod should move thru the gates smoothly.  if not look from beneath the car if the linkage is rubbing against the wiring
